This project aims to develop high field MR techniques to detect nerve lesions in diabetic patients. The MRI findings will be compared to results from conventional evaluations and nerve conduction studies to determine the validity as part of a clinical practice.

Examination of magnetic resoance morphological differences according to neuropathy [ Time Frame: within the first 20 days (plus or minus 6 days) after initial MR scan ] [ Designated as safety issue: No ]

In the 3 year course of the study it is expected to include 90 diabetics with and without neuropathy, 10 patients with hereditary axonal neuropathy and 10 patients with demyelinated neuropathy, as well as 35 healthy control subjects. This amounts to a total of 145 subjects.
